There were many "mysterious" trails that led to different parts of the island. At one point we found two little caves, which was really neat. We were only docked at Bermuda for three days, so we only spent a few hours there. There were lizards scurrying around, and many interesting plants. We also talked to some locals, one of which caught a parrot fish while we were there. the boy had to throw it back in, since there is no fishing allowed at the park. My family and I could probably have spent at least another day just "exploring." A great experience overall.

Blue Hole Park is located on Castle Harbor, down the road from Grotto Bay Resort at the southern end of the Causeway. It's also not far from Crystal and Fantasy Caves. The park is a great place to hike, explore, take pictures, and even get a little caving in.

There were no trail markers or directional signs. This can make it frustrating or adventurous, depending on your personality. Many wonderful sights are tucked around corners or accessed in not immediately obvious ways. It reminded me of playing the Myst games–you're in this lush place and you just need to check everything out to get to the surprises. The blue hole everyone takes a picture of and another pool in a deep cave entrance are easy enough to find. Initially, we walked up the obvious path, which follows the Castle Harbor shoreline. This is where you're likely to see Bermuda longtail seagulls.

Eventually the path turned to dirt, went through the woods, and ended up at Tom Moore's Tavern. Previously we'd passed what appeared to be an empty lawn on the inland side of the trail, so on the way back we decided to check it out. Sort of around a corner, we found a shallow pool full of fish. Trailheads leading to the forest caves were on one edge of this lawn. Without signs, from a distance it simply looks like grass ringed with trees. The trails themselves were mostly narrow dirt paths.

The caves vary–some are small, some are easy to walk around in, some you climb down into while others are up on hills, and there is a huge, open cavern with a pool in it. Back at the Castle Harbor shore, if you are looking out at the water, head left–there is a sea cave with a couple of different entrances tucked into the rocks.

Admission is free, there is a parking lot, there were no facilities (as of June 2011), and only small portion of the park's paths are paved, so I would not regard it as wheelchair or walker friendly. I suggest wearing good walking shoes or sport sandals, bringing water, and bringing a Gorillapod or similar flexible tripod for long exposures in the caves (which have no lights or graded paths). Also consider using insect repellant. Expect to get dirty if you explore the caves.

I have read that people snorkel in Castle Harbor, and there were no signs forbidding it, but we didn't go swimming on our trip.

(Note: We actually visited in June 2011, but I'm pretty late getting to this and Tripadvisor wouldn't let me select that date.)

We were not expecting too much on this walk but were AMAZED by everything - including the walk throughout the forest, the caves, beaches and marshland. Truly diverse and a magical experience! Very unexpected!

Only about a one minute walk from Grotto Bay Resort, this public park features, a great view of Castle Harbour, a small lake for easy fish-viewing, a series of nature trails, and a few caves. It connects with a park known as "Tom Moore's Jungle", which boasts one whole acre of natural Bermuda forest. It's a small park so you could probably devote less than an hour to it, but it's fun to experience these little nature preserves on an otherwise very built-up island. Bring your hiking shoes!
